Designed for stuck on food and heavy stains, including for cast iron pots. Can be used on non-stick pans, just be more gentle with it. Each brush head can be used for 1-3 months. Do not leave any of the wood parts soaking in water, the wood will absorb water and it will cause the wood to swell and crack. Also works to scrub root vegetables and citrus fruits.
